Heater hose routing from Water pump

[trevbeadle]

Can someone please post a photo of the routing for the water pump heater hose?. I have just replaced the wp on my 350 and discovered that the heater hose has become chafed through. The routing from the water pump across before it goes rearwards takes it very near to the bracket supporting the A/C pump. Should it route in front of the A/C compressor mounting, underneath between the bracket and the suspension or behind between the bracket and the block above the exhaust manifold? Its obviously been chafed through before as there is an inline hose joint under the radiator expansion tank as the hose goes rearwards.

Thanks

This is the only photo I've got, it shows how the hose went when I bought the car (can't guarantee it's correct!). I've now removed the A/C so don't need to worry about the routing.

Buy an assembly manual it will answer all your questions.

Alben78,
a screenshot of the relevant page in yours would be helpful. Although I doubt such mundane things are unambiguously specified.

Johng, that is helpful thanks. I have ascertained at least it doesn't route in front of the A/C compressor on mine as it fouls on the A/C drive belt.

Sorry now sold along with car. The assembly manual is totally precise on the manufacturing assembly method to be employed, even gives routing and clearances for most pipe work. Maybe somebody else has a copy they could post?

This is the relevant sheet from my '71 Assembly Manual...


....though not sure how useful it is since it doesn't show the aircon.

Shows it over the top in the 69 book

Not sure if this helps this was the ‘78 L48 which has the later air con compressor. The heater pipe runs from the water pump to the rear of the compressor and over the rocker cover.

Does this help?

Alben78,

that looks identical to my set up .


the return heater pipe runs from this join below the compressor,


to the waterpump


and looks like it should go UNDER the compressor mounting bracket


through that gap!

 

[trevbeadle]

There looks like a forth hose under these 3? The top one is to A/C pump, one under from the rad to expansion tank, the next dne down to the top of the block (heater) and is there another below those.? That would be the one that routes under the A/C pump as you don't have a metal one as Corvettekindom was explaining and the one I@m interested in going to the water pump above the bottom rad hose connection.......

Not sure if this helps or not. Car and FAM now sold..

Alben78,
So yes, that looks like it , the hose that runs up UNDER the compressor bracket (the blue and spotty hose!). Will route it that way thanks.

 

[Alben78]

Glad to be of assistance!

mine has an inline joiner at position //. obviously chafed through before but at least I'm aware of the problem now!!, Thanks everyone for your help.
